“Kiefer was the most unprofessional dude in the world. That’s not me talking trash; I’d say it to his face. I think everyone that’s worked with him has said that.”

A representative for Sutherland has since responded to Prinze, Jr.’s comments, stating, “Kiefer worked with Freddie Prinze Jr. more than five years ago. This is the first time he has heard of Freddie’s grievances. Kiefer enjoyed working with Freddie and wishes him all the best.”

And actress Sara Gilbert, who has also worked with Sutherland on “24,” insists she too is confused by Prinze, Jr’s remarks, insisting, “He was so polite and was always there for our scenes.”
